SOME FUNDAMENTAL PROBLEMS ON THE COMBUSTION OF LIQUID OXIDIZERS IN HYDROGEN
Abstract
The object of the paper is the study of the basic process of combustion of single oxidizer droplets in a quiescent hydrogen atmosphere. There exists an abundant literature on droplet combustion. Most studies refer to the case of fuel droplets burning in air. Some studies consider more sophisticated fuels and there are a few studies on monopropellant droplets. On the other hand, no specific theoretical or experimental studies have been performed on the combustion of oxidizer droplets in hydrogen. This case cannot be included in a general theoretical study on droplet combustion owing to the specific properties of the hydrogen. Its low density and low molecular weight make diffusion conditions especially critical and the assumption of taking average values for gas density and for transport coefficients regardless of mixture composition, which is normally admitted in droplet combustion studies, may introduce important errors for the case of hydrogen and it is shown in the paper.
